I’m sharing this one with you in the hope that it might reach somebody who knows a bit more about Owls than I do. I can’t say I’ve ever heard a bird with what appears to be a saw throat. Maybe this bird is getting old, or possible even have some sort of damage or illness. I’ve enabled the download feature on the audio file, feel free to send it to anybody you may think could shine some light on it. This Tawny Owl has been sounding like this for about two weeks now. I’ve seen it flying but too dark to get a decent look of the bird.
